The Lenovo ThinkSystem RAID 9350-16i is a enterprise-class PCIe Gen 4 RAID controller purpose-built for ThinkSystem V3 platforms, including the SR650 V3 and SR630 V3 server lines. This adapter combines full 16-lane PCIe Gen 4 connectivity with integrated 4GB of DDR4 flash-backed cache memory, enabling deterministic I/O performance and data protection for mission-critical storage operations. The 9350-16i supports up to 16 SAS/SATA drives per controller, delivering sustained performance for demanding database, virtualization, and analytics workloads.
Architecturally, the adapter features dual-port SAS connectivity (12Gb/s per port) and native support for RAID 0, 1, 5, 6, 10, and 50 configurations. The flash-backed cache provides write-back acceleration and battery-backed data protection, ensuring data integrity during unexpected power events. Hardware-based RAID processing offloads computational burden from system processors, freeing CPU resources for application workloads while delivering predictable storage subsystem latency.
Launched in Q1 2023, the 9350-16i has achieved high attachment rates across SR650 V3 and SR630 V3 deployments, establishing itself as the preferred RAID solution for ThinkSystem V3 configurations requiring direct-attached SAS storage scalability and performance.
